     The summer I was ten, my mother decided to bring us to the world of art. My brother and I were not

very excited when we realized what my mother meant. What she meant was not that we could take drawing

classes or painting classes but that we would have to spend one afternoon a week with her at the Fine Arts

Museum. Before each visit to the museum, she made us read about artists and painting styles (风格). It was

almost as bad as being in school. Who wants to spend the summer thinking about artists when you could be

with your friends at the swimming pool?

     First we had to read about ancient Egyptians (古埃及人) and their strange way of painting faces and then

go to look at them at the museum. My 12-year-old brother thought this was so funny, but I was not interested.

Later we had to learn about artists in the Middle Ages who painted people wearing strange long clothing. We

had to look at pictures of fat babies with wings and curly (鬈曲的) hair and with no clothes on flying around

the edges of paintings. I certainly couldn't see what was so great about art.

     On our last visit to the museum, something happened when I saw a painting by a woman called Mary. In it,

a woman was reading to a child. The colors were soft and gentle, and you could tell by the mother's expression

how happy she was just to be with the child. I couldn't stop looking at this painting! I wanted to see every

painting Mary had ever made! It was really worth looking at so many paintings to find a painter who could

interest me so much.
